To save space in your luggage, pack versatile essentials. A black cotton jersey dress works for both daytime and evening. A pashmina shawl serves as an onboard blanket and keeps you warm on those cool L.A. nights. And tinted moisturizer with SPF 30 is a triple threat: foundation, lotion, and sunscreen all in one.

Wear comfortable but cute clothing for your trip. Stay away from linen, which wrinkles easily, and favor low-maintenance, stylish knits and jeans. Dress in layers to adjust to temperature fluctuations.

Tip: Bring a travel-size container of gentle laundry detergent to wash clothes at your destination. One little packet equals two whole outfits you can leave at home.

Step 3: Wear open-toe shoes

Wear your favorite pair of open-toe shoes or sandals. Not only are they easier to pop on and off at security, but once you’re through you can indulge in a pedicure.

Step 4: Stay hydrated

Bring a water bottle with a built-in filter to fill up at a drinking fountain after going through security. It saves money and keeps you hydrated and healthy.

Step 5: Enjoy some &quot;you time&quot;

Before your flight, relax and enjoy some “you time.” Today’s terminals aren’t a black hole of boredom — take advantage of all the modern amenities.

Tip: JetBlue’s Terminal 5 at JFK offers a wide variety of gourmet restaurants. Or stay put, and use T5′s touch-screen monitors to have a meal delivered directly to your gate.

Step 6: Practice proper etiquette

Once on board, make yourself at home, but be considerate of your seatmates — remember that in close quarters, every smell is magnified, every sound amplified, and every movement intensified.

Step 7: Practice airplane yoga

Fight stress and stiffness by doing some basic yoga stretches from your seat. Take a few deep breaths and circle your neck slowly in one direction, then the other. Flex your feet by pointing your toes upward and then away from your body.

Tip: Is being out of touch what gets you stressed? Relax. JetBlue’s new BetaBlue plane offers free wireless so you can e-mail and IM during the flight.

Step 8: Freshen up before landing

Before you land, take time to freshen up. Wash your face with disposable cloths, or use a refreshing spritzer. Add concealer under your eyes and a little cream blush to your cheeks for a rosy glow.
